Tore a \'91 1 ton apart yesterday... Figured I'd post a few "tidbits" that I found while ripping this rig apart. It was a SRW 3+3. 454/4L80E/205/4.10's. Had the funny transmission crossmember that hangs lower on one side. Short adapter. Fixed yoke 205, with the CV (?) joint front shaft. Hydroboost. Hydroboost with power steering cooler. Cooler was weird in my opinion....no fins, just a few extra lengths of pipe underneath the radiator. Added capacity more than anything if you ask me. Knock sensor is about the same location as on a SBC, right near the forward end (as installed) of the starter. Oil pressure sender/switch (3 prong) is located on the drivers side lower edge of the timing chain cover. Fuel lines at the tanks were hose clamped. Not going to say they were factory though, as the clamps didn't look original, and the lines looked newer. But the sending unit fittings aren't threaded like the ones I've seen, so who knows? 205 has both the 4wd indicator switch, as well as the toner ring setup. No more searching for that stuff for me! /forums/images/graemlins/smile.gif Anyone have any questions on the 1 ton that could use clarifying? (as in construction, or what parts it had) My dad is heading back over there tomorrow to take the last of the TBI stuff off of it. No parts left on it, as I grabbed JUST about everything I could. Guy was loading it up on a flatbed when I left, so there is no way to get under it again. Just thought I'd post that info while its still in my head. Also got a picture of the emissions label of a 1990 350 Suburban, so that will be up soon for all to use.
